Engine failure indications

[KLOS]

Question for the professional pilots/ engineers.

With modern technology would the expectation be that an in flight engine failure would generally have been flagged in advance by the a/c instrumentation or is it just a likely to fail without any advance instrumentation warning?

Thanks

Change in airspeed, noise change (the sound of one negine winding down and the other increasing to take the load), change in a/c attitude due to reduction in thrust, depnding upon what causes the failure, change in indicated pressures, fuel flows, warning indications illuminating, engine instrumentation, modern a/c will show theres a problem in the health monitoring equipmentwhich will be alerted on the MFD's. Sometimes a pilot will just get the feeling through "seat of his pants" that something is amiss.

KLOS - not normally. The only 'advance warning' you might get is an abnormal reading on one of the instruments such as falling oil pressure, rising oil temperature, increasing vibration, abnormal EGT. etc. Mechanical failure is normally very sudden and unexpected!

The modern engine monitoring systems will be telling parameters to base engineers who may be able to 'foresee' a problem.
